Settings are as should be on each of 3 computers. This problem happened overnight. I created a new save folder located under local and directed saved copies to the new folder. All copies are now saved to the new save folder. What I don't understand is what changed that necessitated this creation of a new save folder located under local. And why did it happed overnight on all 3 computers.

I get the following error messages: The current operation on Inbox did not succeed. The mail server for your account @windstream.net responded: Unrecognized command ID.

The other error message is: The current operation on sent did not succeed. The mail server for your account @windstream.net responded: Unrecognized command ID
